It has been awhile since I had anything really worth
noting, but about two weeks ago I had a doozy; it was
after the big windstorm we had in the DFW area and
specifically in the Plano/Allen area.
On 80 Meters - a continuous buzzing noise had appeared
with a signal strength = S7 SSB mode and = 5 dB over S9
in AM mode - I literally took this bull on by the horns and
DF'd / tracked it down on the second day. Turms out it was
a little over a mile away ...
The source, on a pole across from 201 E. McDermott (a big
church in Allen) and a block or so east of the railroad tracks,
could be heard up and down McDermott and in the downtown
Allen area on the AM broadcast band. In fact, a mile away
the source could still be heard on the AM Broadcast band on
a clear frequency.
Full report available here, including pictures of the 'source' after
locating it (a power pole with an obvious loose wire) along with
signal strength measurements and a map showing the distance
(over a mile) between me and the 'source':

The uploaded file at this URL should be good for thirty (30) days,
beyond that I can't warranty anything.
